IMPROVEMENT IN LANTERNS.

Specification forming part of Letters Patent No. 122,931, dated January23, 1872.

To all whom it may concern:

Be it known that I, CHARLEs S. S. BARON, of Bellaire, in the county ofBelmont and State of Ohio, have invented a new and useful lmprovement inLanterns, of which the following is a specification:

My invention relates more especially to that class of lanterns known asrailroad lanterns; and my said invention consists in constructing theguard-tubes connecting the cap with the base of alantern of distinct,separable sections, the upper sections fitting within and sliding intothe lower sections7 the two thus interlock ing being held to each otherso as to firmly hold the globe between thecap and base, and admit of itsinstant removal for cleansing and lighting the lamp 5 and'further, inthe arrangement of a bow-spring, secured to the band of the basecentrally between its bent and beveled ends, which are free to enter orbe withdrawn from slots or mortises formed in both sections of tubes, insuch manner that when the ends of the upper sections of tubes enter thelower sections they will automatically compress the spring through itsbeveled bent ends until the slots in both sections of tubes match eachother, when the ends of the spring, being released from contact with theends of the upper sections of tubes, enter both slots, and thus firmlyhold the interlocking sections the spring being so arranged as to bereadily operated by two ingers of one hand to release the ends from theslots, and thus allow the sections to be separated, while theirinterlocking is accomplished automatically.

In the accompanying drawing, Figure 1 represents a side elevation of alantern embracing my invention. Fig. 2 represents a similar view, theglobe being removed and the connecting guard-tubes separated from eachother. Fig. 3 represents a vertical central section of Fig. l; and Fig.4 represents a horizontal section in line a". lv of Fig. l.

The ordinary cup a, foot b, and perforated band c are formed in theusual manner of sheet metal, and at opposite sides of the band shorttubes d are soldered to the foot a, in vertical positions, and braced tothe band c by braces d. To the reilector f of the dome g are soldered,at corresponding points, tubes c', extending downwardly, and of a littleless diameter or mortises 7L, whereby the tubes e are prevented Jfromslipping out of the tubes d unless the spring be so compressed towardthe periphery of the band c, as to withdraw the bent ends 'i from theslots or mortises h, which is easily accomplished by reason of thecentral connection of said spring. The globe 7c rests on the band c, itslower end m extending into the same, and its upper' narrow straight endl extends into the dome g in such a manner that, when the parts are puttogether as shown in Figs. l and 3, the globe is held rmly between thedome g and band c, and can be removed only by compressing spring j toremove its ends i from the slots or mortises It, and elevating the domeg with its reiiectorf and tubes e from the tubes d of the foot. The endsof sprin gs j, which are, as above described, bent at i, pass throughslots j in braces d', so as to prevent any downward movement of the endsof the spring under the pressure of the tubes e upon them whileinterlocking the parts. Thus the slotsj act as braces to the spring,insuring the entrance of its ends t into the slots or mortises It oftubes e without fail every time the tubes c are depressed into the tubes(l. The usual bail or handle a is suitably pivoted to the dome g. rlhetubes d c, when the parts are put together, not only unite the severalparts in connection with spring j which holds them together iirmly, butalsovserve as guards for the protection of the globe. The beveled upperedges of the ends 'i of spring j allow of the automatic interlockingIoi' tubes e and d by merely depressing the former into the latter untilthe ends can pass through the slots l1J in both, while the straightlower edge of the ends i prevents any accidental removal of the endsfrom the slots unless the spring j is compressed from outside.

To enable manufacturers to make a low-pri ced lantern with a removableglobe guarded with wire in the usual manner, they must construct theparts of iiimsy material, thereby considerably weakening them 5 but bymy improved construction I am enabled to produce a very cheap lantern,yet avery stron gone-a lantern which has all the advantages ofahigh-priced railroad lantern, such as strength, large lightradiatingsurface of the removable globe, easy manipulation for lighting andcleansing, and yet can be furnished at an exceedingly low price,comparatively.

It is obvious that the base of the lantern may be provided with socketsto receive the distinct and separable tubular guards in any suitable andconvenient manner, so long as the feature of interlocking and separationof parts is effected. Y Y

Having described my invention7 I claim- I. In a lantern having` outertubular guards Yfor connecting the dome with the foot to secure theglobe, I claim such tubular guards made in distinct and separablesections, so as to be united to each other and to admit of theirseparation, essentially as described.

2. In a lantern in which the tubular guards are made in distinct andseparable sections, as described, I claim, in combination therewith,

the automatic locking-spring, arranged to cperate essentially asdescribed.

3. The automatic locking-spring, having its free ends provided withtheir upper edges beveled d ownwardly and their lower edges straight toact in conjunction with the ends ofthe tubular guards to effect theirautomatic locking and to prevent unlocking of said connection, asdescribed.

4. In combination with an automatic lockingspring, arran ged asdescribed, I claim the braces d' to support its free ends against thevertical resistance of the tubular guards in the operation ofinterlocking the same with the tubes of the base, essentially asdescribed.

5. The combination, in a lantern, ofthe separable and distinct tubularguards d e with the dome, the base, and the automatic lockingspring j,the several parts being constructed and arranged for use essentially asdescribed.
